DETAILED DESCRIPTION

Certain embodiments of the present invention will be described below in more detail with reference to the accompanying drawings.

A user terminal based on an embodiment of the present invention, such as a smart phone, can easily adjust the size, position, rotation, etc., of a displayed UI (User Interface). In particular, embodiments of the present invention may provide various methods of adjusting a UI by to easily manipulate a UI displayed on the user terminal with one hand. Here, the UI encompasses all types of UI such as entities (interfaces, widgets, icons, patterns, etc.), pattern unlock screens, widget screens shown after an unlock, regular UI screens, etc., and can also mean a partial UI from among a whole UI displayed on a screen. The UI can correspond to the size of the screen on which the UI is displayed.

Certain embodiments of the present invention will be described below in more detail with reference to the accompanying drawings.

FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 1D illustrate a method of adjusting a UI according to an embodiment of the present invention. For easier description, the method of adjusting a UI will be described using the pattern unlock as an example of a UI.

Referring to FIG. 1A, the unlock patterns 102 for a pattern unlock can be defined as one UI 100, and the UI 100 may be displayed on the screen of a user terminal, such as a smart phone for example. The screen can be divided into an area for displaying the UI, a top area for displaying the remaining battery power, etc., and a bottom area for displaying the phone icon, etc., as shown in FIGS. 1A to 1D.

When the UI 100 is displayed in a large size as illustrated in FIG. 1A, the user may have to use both hands to control the user terminal conveniently, but when only one hand is available for using the user terminal, such as on a bus, or a subway train, etc., it can be difficult to control the user terminal.

Thus, a method of adjusting the UI based on an embodiment of the present invention may adjust the size, position, etc., of the UI 100 according to an input by the user, as illustrated in FIG. 1B to FIG. 1D. Of course, the UI adjustment method can involve reducing the UI to generate a reduced UI 100 a, 100 b, and 100 c, and magnifying a reduced UI 100 a, 100 b, and 100 c or returning it to its original size. Here, the rate of magnification and rate of reduction can be varied according to the user's input or can be fixed to preset values.

The UI 100 a, 100 b, or 100 c can be arranged in various positions, as illustrated in FIGS. 1B to 1D. However, assuming that the user touches the user terminal with one hand, it may be preferable to position the reduced-size UI 100 a, 100 b, or 100 c on the left or right side of the screen.

According to an embodiment of the present invention, the user input is a concept that encompasses both user inputs made as a user touches the screen of the user terminal and user inputs made as a user brings a touch means, such as a finger, etc., near to the user terminal without actually touching the screen of the user terminal. For easier description, it will be assumed below that the user input is an input made when the user touches the screen of the user terminal or touches a keypad, etc., of the user terminal.

A description is provided below, with reference to the accompanying drawings, of various methods for adjusting a UI according to certain embodiments of the present invention.

FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 6 illustrate a method of adjusting a UI according to a first embodiment of the present invention. For easier description, the UI adjustment method will be described using the pattern unlock as an example of a UI. Referring to FIG. 2, there can be left and right adjustment areas 200 and upper and lower adjustment areas 202 for adjusting the size and position of the UI. More specifically, the adjustment areas 200 and 202 can be positioned in perimeter portions of the UI, and can be positioned within a preset distance from the bezel of the user terminal. The adjustment areas 200 and 202 can be actually represented on the screen, such as by arrows as illustrated in FIG. 2, or can be virtual areas that are not represented by arrows.

Although FIG. 2 represents the adjustment areas 200 and 202 as arrows, they can be represented in other forms. For example, entities similar to a UI for zoom adjustment on a camera can be shown in the adjustment areas 200 and 202. Also, the adjustment areas 200 and 202 can preferably be positioned in areas other than the area in which entities such as icons, etc., are represented, and can be areas along the entire right or left side or partial areas on the right or left side.

According to an embodiment of the present invention, if a user uses a touch means, such as a finger or a touch pen, etc., to touch one of the adjustment areas 200 and 202 and move in a particular direction while maintaining contact, i.e. if the user provides a particular input to the user terminal, then the UI 100 can be reduced or magnified to the touch point of the touch means.

For example, if the user touches a particular point in the adjustment areas 200 and 202 and moves the touch means in a downward or a leftward direction while maintaining contact, the UI 100 can be represented in a reduced form near the touch point, and if the user moves the touch means in an upward or a rightward direction while maintaining contact, the UI 100 can be represented in a magnified form near the touch point. The reduction and magnification rates can be determined according to the distance moved by the touch means from the initial touch point. Of course, the direction for magnification/reduction can be set opposite to the above.

Also, the final position of the magnified or reduced UI can be determined according to the initial touch point or according to the final touch point. In cases where the position of the magnified or reduced UI is determined according to the final touch point, the UI can move while it is being magnified or reduced, as it follows the position of the touch means that moves while in contact with the user terminal.

In one example, as illustrated in FIG. 3, if the touch means moves in a particular direction while touching a middle point of the left adjustment area 200 a, then the UI 100 can be reduced to the middle left. Of course, although FIG. 3 illustrates a reduction as an example, it should be appreciated that reversing the arrows in FIG. 3 would represent a screen for magnification.

In another example, as illustrated in FIG. 4, if there is a movement in a particular direction while touching a lower point of the left adjustment area 200 b, then the UI 100 can be reduced to the lower left.

In yet another example, as illustrated in FIG. 5, if there is a movement in a particular direction while touching a middle point of the right adjustment area 200 c, then the UI 100 can be reduced to the middle right.

In still another example, as illustrated in FIG. 6, if there is a movement in a particular direction while touching a lower point of the left adjustment area 200 b, then the UI 100 can be reduced to the lower right.

According to another embodiment of the present invention, if the user uses the touch means to touch a point on one of the adjustment areas 200 and 202 and then make a touch again, then the UI 100 can be magnified or reduced to the touched point, with the rate of magnification or reduction corresponding to the number of touches.

According to yet another embodiment of the present invention, if the user uses the touch means to touch a point on one of the adjustment areas 200 and 202, the UI 100 can begin its magnification or reduction to the touched point, and when the user releases the touch, the change in size of the UI 100 can be stopped. For example, when the user touches a portion of the adjustment areas 200 and 202, a reduction can begin, and when the user touches again, a magnification can begin. Thus, the user can select a magnification or reduction function by making a touch or a re-touch and control the duration of the pressing to magnify or reduce the UI 100 to a desired point in a desired proportion.

According to still another embodiment of the present invention, if the user moves the touch means to a particular point in relation to the touch point, the UI 100 can be magnified or reduced to the point at which the touch means is positioned last, where the rate of magnification or reduction can be determined according to the distance by which the touch means was moved.

According to another embodiment of the present invention, if the user uses the touch means to touch the adjustment area on an upper part of the screen of the user terminal and move to the left while maintaining contact, then the UI 100 can be magnified or reduced as it is moves to the left. Of course, if the user moves to the right while touching the adjustment area on the upper part of the screen of the user terminal, then the UI 100 can be magnified or reduced as it is moves to the right.

According to yet another embodiment of the present invention, if the user uses the touch means to touch the adjustment area on a lower part of the screen of the user terminal and move to the left while maintaining contact, then the UI 100 can be magnified or reduced as it is moves to the left. Of course, if the user moves to the right while touching the adjustment area on the lower part of the screen of the user terminal, then the UI 100 can be magnified or reduced as it is moves to the right.

In summary, a UI adjustment method based on this embodiment may use the touch point, to magnify or reduce the UI to or near the touch point. That is, the UI adjustment method according to an embodiment of the present invention may use the touch point in representing a magnified or reduced UI, where the position of the magnified or reduced UI may be determined according to the touch point of the touch means touching the adjustment area. Here, the touch point can include all points, from the initial touch point to the final touch point, and whether the UI is to be magnified or reduced can be determined according to the direction in which the touch means moves from the touch point of the touch means. Also, the rate of magnification or reduction can be determined by various methods based on the distance of a movement, the number of touches, the duration of a touch, etc.

Of course, the image of the UI being magnified or reduced can be displayed as is on the user terminal, or the magnified or reduced UI can be displayed on the screen without having the image of the magnification or reduction shown. Also, while it is described above that the UI may be changed to the point where the user made a touch, the direction of adjustment of the UI can also be fixed, irrespective of the user's touch point.

Although the above describes a size change and positional movement for one UI, it is also possible to change the size, position, or arrangement of multiple UI's.

While it is described above that the rate of magnification or reduction of a UI may vary according to the movement distance, etc., of the touch means, the rate of magnification or reduction can also be set initially to a fixed value. That is, if the user touches a portion of an adjustment area, the UI can be magnified or reduced to the touch point, but the rate of magnification or reduction can be fixed. Thus, even if the user moves the touch means, the rate of magnification or reduction can remain unchanged. However, when the touch means is moved, the UI can be magnified or reduced to the final touch point of the touch means.

Although it is not mentioned above, the beginning of the UI adjustment can be triggered as the user presses a particular button on the user terminal, selects a particular menu item, or issues a UI adjustment command by voice.

Also, while FIG. 1 to FIG. 6 illustrate a touch input method for adjusting the size of a UI that is similar to a method for adjusting a camera zoom, it is also possible to apply other methods. It is possible to have the screen increased if there is a prolonged touch on a particular area, such as the upper end portion of an arrow for example, and have the screen decreased if there is a prolonged touch on a lower end portion of the arrow.

When the screen size has been changed according to an embodiment of the present invention, the changed screen size can be applied for a particular UI only and for a single use. That is, the UI shown after the user decreases the pattern unlock screen and performs an unlock can be represented in its original size.

Also, if the user turns off the user terminal and turns it on again, the pattern unlock screen can be represented in its original size before the reduction. Of course, the settings can be configured such that the changed UI size always applies to all UI's.

When the user decreases the size of a UI on the user terminal and executes an application, the application can be executed in its original screen size.

Although it is not illustrated in the drawings, it would be apparent to those skilled in the art that an embodiment of the present invention can also be applied to adjust the size of photographs and web pages when viewing photographs stored in the user terminal or when surfing the web, particularly in situations where multiple touches cannot be made.

FIG. 7A and FIG. 7B illustrate a method of adjusting a UI according to a second embodiment of the present invention.

Referring to FIG. 7A, a UI 700 including unlock patterns 102 can be displayed on the screen of a user terminal.

When a user presses a particular button, etc., for adjusting the UI 700, an icon 702 can be shown that allows the adjusting of the UI 700.

In this situation, if the user touches a particular point, such as point 704 for example, and pulls towards an inner direction of the UI 700 while maintaining contact, then the UI 700 can be reduced in the direction of the pulling, and if the user touches and rotates the icon 702, then the UI 700 can be rotated, as illustrated in FIG. 7B.

In summary, the UI adjustment method of this embodiment can provide an icon 702 for adjusting the UI 700, to allow an adjustment of the size or position of the UI 700 by using the icon 702.

Of course, the UI 700 can also be made to rotate if the user touches a particular point on the UI 700 and moves in a rotating direction while maintaining contact, instead of using the icon 702 to rotate the UI 700.

That is, a UI adjustment method of this embodiment can adjust the size and position of a UI 700 and rotate the UI 700 to a desired direction.

FIG. 8A and FIG. 8B illustrate a method of adjusting a UI according to a third embodiment of the present invention.

As illustrated in FIG. 8A, if the user presses a particular button, etc., then a menu 800 for adjusting the UI can be displayed on the screen of the user terminal.

The menu 800 can include a sub-menu 810 for adjusting the position of the UI and a sub-menu 812 for adjusting the size of the UI, as illustrated in FIG. 8B.

That is, the user can make a selection in the menu 800 to adjust the UI to a desired position and a desired size. Of course, the composition of the menu 800 can have many variations.

Calling the menu 800 and making a selection can also be performed by the user making a voice input, rather than pressing a button or making a touch input.

FIG. 9 illustrates a method of adjusting a UI according to a fourth embodiment of the present invention.

Referring to FIG. 9, an adjustment bar 900 can be displayed on a portion of the screen of the user terminal. Preferably, the adjustment bar 900 can be shown on a perimeter portion of a UI displayed on the screen of the user terminal.

The adjustment bar 900 can include a position adjustment bar 910 that adjusts the position of the UI and a size adjustment bar 912 that adjusts the size of the UI.

If the user selects an icon for a particular direction on the position adjustment bar 910, the UI can move in a corresponding direction, and the size of the UI can gradually be magnified or reduced according to the duration by which the size adjustment bar 912 is pressed. The selection of magnification or reduction can be changed in various ways, an example of which can involve recognizing a selection for the reduction function if the size adjustment bar 912 is touched an odd number of times and recognizing a selection for the magnification function if the size adjustment bar 912 is touched an even number of times.

Although the foregoing does not mention the adjustment bar 900 as being implemented with a rotation function, the adjustment bar 900 can further include a rotation adjustment bar for implementing such rotation function.

According to another embodiment of the present invention, the adjustment bar 900 can include only the position adjustment bar 910. For example, if the user selects an icon for a particular direction on the position adjustment bar 910, the UI can be moved left, right, up or down, and the UI size can be reduced or magnified in a fixed rate.

According to still another embodiment of the present invention, the adjustment bar 900 can include only the size adjustment bar 912. For example, if the user uses the size adjustment bar 912 to adjust the size, the UI can be automatically moved to a preset fixed position.

According to yet another embodiment of the present invention, the adjustment bar 900 itself can be positioned biased to the left or to the right, to allow the user easier use with one hand.

FIG. 10 illustrates a UI screen according to another embodiment of the present invention.

While unlock patterns are illustrated as an example a UI in FIG. 1 to FIG. 9, the UI can include icons, at least one widget, a screen including widgets, etc., as illustrated in FIG. 10.

In the case of icons, widgets, etc., such as those illustrated in FIG. 10, the UI can be a widget screen showing widgets, and the size, position, or rotation of the widget screen as a UI can be adjusted. Here, the widget screen as a UI refers only to the area within the adjustment area represented by arrows in FIG. 10, and the top area showing the battery indicator icon, etc., and the bottom area showing the home icon, etc., may not be included in the UI for the purposes of the present invention.

The features described with reference to FIG. 1 through FIG. 9 are also applicable to the UI of FIG. 10. Also, the features described with reference to FIG. 10 and described subsequently are also applicable to the UI of FIG. 1 through FIG. 9.

According to another embodiment of the present invention, in addition to the UI within the adjustment area, the top area showing the battery indicator icon, etc., and the bottom area showing the home icon, etc., as well as the icons, etc., within these areas can also be adjusted in position or size.

FIG. 11A and FIG. 11B illustrate a method of adjusting a UI according to a fifth embodiment of the present invention.

As illustrated in FIG. 11A, if the user shakes the user terminal left and right or up and down, the UI 1100 can be reduced or magnified during the shaking, and if the user, while shaking the user terminal left and right or up and down, stops after moving the user terminal in a particular direction, such as direction 1102 for example, then the reduced or magnified UI 1100 can be positioned in said particular direction, as illustrated in FIG. 11B.

That is, the user can use a shaking method to adjust the size of the UI 100 and move the position of the UI 100, without having to press a button on the user terminal or manipulate a touch screen. By using this method, the position and size, etc., of the UI 100 can be adjusted with just one hand, making it considerably convenient for the user who is on a bus, etc.

According to another embodiment of the present invention, the magnification or reduction of the UI 1100 can be determined according to the direction in which the user terminal is shaken. For example, if the user shakes the user terminal left and right, the UI 1100 can be reduced, and if the user shakes the user terminal up and down, the UI 1100 can be magnified.

In summary, a UI adjustment method of this embodiment can employ a method of shaking the user terminal to adjust the position and size, etc., of the UI. Of course, it is possible for the UI adjustment method to rotate the UI as well.

FIG. 12A and FIG. 12B illustrate a method of adjusting a UI according to a sixth embodiment of the present invention.

Referring to FIG. 12A, an adjustment part 1200 can be displayed on a portion of the screen of the user terminal.

The adjustment part 1200 may recognize a touch input by the user, and the user can move a touch means in a particular direction while maintaining contact in the adjustment part 1200 to magnify or reduce the UI in the touched direction, as illustrated in FIG. 12B.

According to another embodiment of the present invention, the user terminal not only can adjust the UI but also can adjust the position, etc., of the adjustment part 1200.

FIG. 13A and FIG. 13B illustrate a method of adjusting a UI according to a seventh embodiment of the present invention.

If the user terminal is tilted in a particular direction, as illustrated in FIG. 13A, then the UI can be moved in the tilted direction, as illustrated in FIG. 13B. Also, the size of the UI can be magnified or reduced, where the rate of magnification or reduction can be set beforehand. That is, the UI may be magnified or reduced in the direction in which the user terminal is tilted, and the position of the magnified or reduced UI may be determined according to the direction in which the user terminal is tilted.

For example, the user terminal can be tilted left, right, up, or down from an orientation in which the display unit of the user terminal faces the sky, or can be tilted left, right, or up from an orientation in which the user terminal stands upright. In such cases, the UI can be magnified or reduced towards the tilting side.

The tilted state of the user terminal can be detected by a sensor, for which the user terminal can include a gyroscope sensor for example. As the gyroscope sensor detects the tilting direction of the user terminal, the position and size of the UI can be adjusted. That is, if the user terminal is tilted to the left, as illustrated in FIG. 13, the UI can be moved left while being reduced in a leftward direction. Although it is not illustrated in the drawings, the user terminal can be moved right while being reduced in a rightward direction if the user terminal is tilted to the right. In other embodiments, the position of the magnified or reduced UI can be set differently according to the tilting direction of the user terminal.

FIG. 14 illustrates a method of adjusting a UI according to an eighth embodiment of the present invention.

As illustrated in FIG. 14, the user can move the position of a UI, of which the size, etc., has been adjusted, on the user terminal by using a touch means.

According to another embodiment of the present invention after the UI 1400 has been adjusted, the adjusted UI 1400 can be moved according to the direction in which the user shakes the user terminal.

FIG. 15 illustrates a method of adjusting a UI according to a ninth embodiment of the present invention.

As illustrated in FIG. 15, the user can copy a UI 1500 to create a UI copy 1502. By such copying, the UI's 1500 and 1502 may be present in multiple positions, so that the user can select a desired icon, etc., anywhere with one hand.

FIG. 16A and FIG. 16B illustrate a method of adjusting a UI according to a tenth embodiment of the present invention.

As illustrated in FIG. 16A and FIG. 16B, a menu 1600 can be represented on the screen of the user terminal, and if the user selects a particular menu item, the UI 1610 can be arranged on the screen in a corresponding number. Of course, the position and the rate of magnification or reduction can be set beforehand for each number of UI's 1610.

FIG. 17 is a block diagram illustrating a user terminal according to an embodiment of the present invention.

Referring to FIG. 17, a user terminal can include a control unit 1700, a UI unit 1702, a display unit 1704, an input unit 1706, a recognition unit 1708, a menu unit 1710, a UI control unit 1712, and a storage unit 1714. The UI adjustment methods described above with reference to FIG. 1 to FIG. 16 can be applied to the user terminal illustrated in FIG. 17, and other embodiments can have additional or omitted components with respect to FIG. 17.

The UI unit 1702 may display a UI, such as an unlock pattern, widget, icon, etc., or manage a displayed UI. Here, the UI can be a pattern unlock UI or a UI representing one or more application icons, or an entity, a group of multiple entities, or an entity screen showing at least one entity.

The display unit 1704 may serve to display images, etc., and can be an OLED, LCD, PDP, etc., not being limited to a particular type.

The input unit 1706 may serve to receive the user's input.

The recognition unit 1708 may recognize the user's input and extract the user's command.

The menu unit 1710 may manage a menu that is to be shown on the display unit 1704, a menu for managing the UI, and the like.

The UI control unit 1712 may adjust and manage the size, position, arrangement (rotation), etc., of a UI according to the user command corresponding to the user's input.

According to an embodiment of the present invention, the UI control unit 1712 can show a UI after moving the magnified or reduced UI to the direction of a point at which the touch means made contact in an adjustment area on the display unit 1704 or, if the touch means was moved, the direction of the point at which the touch means was positioned last. That is, the position of the magnified or reduced UI may be determined according to the touch point of the touch means touching the adjustment area, and the UI control unit 1712 may magnify or reduce the UI in a direction towards a position corresponding to user input. Here, the rate of magnification or the rate of reduction of the UI can be determined in accordance with the movement distance of the touch means, and the magnification or reduction of the UI can be determined in accordance with the direction in which the touch means was moved from the touch point of the touch means. Also, the adjustment area can be positioned in a perimeter portion of the UI and can be positioned within a preset distance from the bezel of the user terminal.

According to another embodiment of the present invention, the UI control unit 1712 can show the UI after moving the magnified or reduced UI in a direction towards a position corresponding to user input.

According to yet another embodiment of the present invention, the UI control unit 1712 can show the UI after moving the magnified or reduced UI in a direction in which the user terminal is tilted.

According to still another embodiment of the present invention, an adjustment part capable of touch recognition can be displayed on a portion of the screen of the display unit 1704, and the UI control unit 1712 can adjust at least one of the position, size, and arrangement of the UI in accordance with the input of the touch means touching the adjustment part.

According to yet another embodiment of the present invention, a multiple number of adjustment icons can be shown in a perimeter portion of the screen of the display unit 1704. For example, there can be three adjustment icons each on the top portion and bottom portion of the display unit 1704, with one adjustment icon on the middle left and one adjustment icon on the middle right. If the user selects a particular adjustment icon, the UI control unit 1712 can change the position of the UI to or near to the position of the selected adjustment icon, and the UI can be magnified or reduced to a preset size. Also, it is possible to allow the user to arbitrarily set the number, arrangement position, and form of the adjustment icons.
